Do you have that NFS storage accessible to vdsm user? the folder you are mounting better be owned by vdsm:kvm Best, Fil -- Dmitry Filonov Linux Administrator SBGrid Core | Harvard Medical School 250 Longwood Ave, SGM-114 Boston, MA 02115 On Fri, Jun 28, 2019 at 9:16 AM Andy Michielsen <andy.michielsen(a)gmail.com&gt; wrote:

Hello All, Thank you for the replies. I read the url and I think I did it all as discribed. I did a ssh into the synology and changed the owner and group for the volume I created and the folder I'm sharing with NFS. I did the the mounting test on the engine and also on the node. And I unmounted it afterwards. But I will try and log on with the vdsm user. Have to look for the password and then I will try and mount again. Kind regards.

When you added the permissions on the NFS export did you map the user and group ID to those names? IE the userid is 36? ________________________________ From: Andy Michielsen <andy.michielsen(a)gmail.com&gt; Sent: Tuesday, July 2, 2019 9:29 AM To: Staniforth, Paul Cc: users Subject: [ovirt-users] Re: Using a synology as an nfs storage Hello, I'm still strugling with adding a nfs share from my synology share.

I have done my configuration and I'm able to mount the share manually on the node with a command. Also on the server with the engine on I can mount it manually. But when I want to do it through the webinterface to add a data domain it say the permissions are wrong. Any idea's on how to figure this out ? Kind regards.

Hello, I got it working after changing the permissions from the shared folder from 777 to 755 ? Wasn't expecting that. So to get a DS1219+ providing a NFS share for my oVirt environment and this is how I did it. First create the volume and the NFS share in the synology. Create a user vdsm and a group kvm. And then the magic happens on the commandprompt from the synology. SSH into the synology and change the uid and gid to 36 in the /etc/passwd file for the user vdsm. Also change the gid in the /etc/group file to 36 for the group kvm. Then change the permissions for the created share, in my case volume1, to 755 instead off the 777+ synology gives. Restart the nfs server in the ssh session with synoservice --restart nfsd. And thank you all very much for the assistance. It put me on the right track. Kind regards.

Wow. Good to know. It is actually a really bad and misleading error message. Why don't you open a ticket for it? It should be really easy to fix but might save some people a lot of time trying to figure it out. Fil On Wed, Jul 3, 2019, 3:19 AM Andy Michielsen <andy.michielsen(a)gmail.com&gt; wrote:
